MOBILE THEFT SIGNAL.

bar 11, the sections of the signal will be AKE and locked relative to one another. I

United The means for thus moving block 14 into a county locking or unlocking position may comprise 60 ia, have a lock barrel 17 threaded into section of rents in the signal and having a swinging arm 18 ich the actuated by the turning of the key in the keyhole 19 of the lock. The swinging arm partic- 18 is slotted as shown at 20 and engages a inection pin 21 projecting from block 14;, so that the tlld the swinging movement of arm 18 as controlled ision of by the turning of the key in the lock will zructure move block 14 back and forth into either position locking or unlocking position.

It will be noted that the construction, 'erstood as thus set forth, provides an extremely durthe a able device which affords an efiicient signalling device adapted to be locked onto the 16 theft tire of a wheel. e upon Various changes may be made without de- )wn in parting from the spirit of the invention as claimed.

What is claimed is: ad upon 1. A device of the character described ar i comprising separable sections adapted to l tire 3. form an annulus, one of said sections having tions 4 a toothed bolt extending through a bore of ide an the other section, and a locking block in afl'ordsaid second section adapted to engage said he sectoothed bolt.

which 2. A device of the character described 01 opcomprising separable sections adapted to ensions form an annulus, one of said sections having toward a toothed bolt extending through a bore of 0 ith end the other section, a toothed locking block blocks movable in said second section for engagenst the ment with said toothed bolt, and a lock he secadapted to move said locking block. es-to 3. A device of the character described around comprising two sections fitting together and forming an annulus adapted to surround a 5preitire and rim and affording a blade-shaped or me projection for engagement with the ground, 4ections extensions extending inwardly from said d abutsections, lateral arms extending from the tongue inner ends of the extensions and having nection end contact members adapted to engage bar 11 the sides of the wheel disc, said sections shown being joined by a tongue and recess joint, 12 in a bar extending from one of the sections section through a bore in the other section and k 14: is having retaining teeth, a block slidably ck has mounted alongside the bore and having rete with taining teeth to engage the teeth ofthe bar, t when and a lock for operating the block. ith the 4. A device of the character described,

comprising two sections adapted to fit around a tire, there being tongue and groove connections between the sections, an arm extending from one section through aborc in the other section and havingretaining teeth,

- a block slidingly mounted at the side of the comprising two sections adapted to engage a tlre and Wheel rim, said sections being extensibly connected together by a rod extending from one section through a bore in the other section, retaining teeth upon the rod, and locking means for engaging the retaining teeth so as to hold the sections together upon a Wheel.

In testimony whereof We have signed our names to this specification.
